SIM

Just upgraded, and changed my contract, can I put my current SIM in my new phone when it arrives?

Yes, if the old SIM fits in the new phone, that is all you need to do.

If you have upgraded to a 5G phone with a 5G tariff, the new SIM will be a 5G SIM - you will need to do a SIM Swap to transfer your number onto the new SIM if you want to avail of 5G speeds, where available - Guide: Sim Swap: a mini guide 2017 update 

Good luck, @Ellaa.
